In vivo nonmelanoma skin cancer diagnosis using Raman microspectroscopy.

abstract：BACKGROUND AND OBJECTIVES:CO2 laser cordectomy has been the workhorse of laser surgery for early glottic squamous cell carcinoma (GSCC) since the early 1970s. During the last decades, potassium titanyl phosphate (KTP) laser surgery for early GSCC gained popularity, introducing the tumor ablation technique. Yet, there a...
